| Popis: | Here we present the first results of GRB afterglow observations with GROND. Gamma‐Ray burst Optical and Near‐infrared Detector (GROND) is an instrument with 4 optical CCDs and 3 near‐infrared detectors with the main aim of observing GRB afterglows and determining their redshift. With its dynamic scheduling and on‐the‐fly data analysis system, GROND combines the sensitivity of the 2.2 m telescope with a robotic observation and analysis scheme. GROND has been mounted on ESO/MPI 2.2 m telescope at La Silla since May 2007. It automatically observed 10 of the 35 GRBs that happened before October 30. Here we will present an overview of GROND observations, concentrating on the preliminary results of two GRBs: the putative host galaxy of the short GRB 070729 and the complex optical/near‐infrared light‐curve of GRB 070802. |
